The paper - Money Creation in the Modern Economy

The paper is impressive in that it also makes a number of insightful points apart from the issue of the money multiplier – points not often seen elsewhere – and treated here matter-of-factly and effectively. Moreover, its scope extends well beyond money creation and into a wider description of the dynamics of money circulation and bank risk management.
The section on quantitative easing in particular is excellent because (unusually) it immediately identifies a fundamental aspect of QE overlooked by most commentators – which is that QE routinely creates broad money as well as bank reserves. I suspect future economic history books will look back on this QE episode and point to a general failure by present day analysts and economists to consider this balance sheet aspect more thoroughly in figuring out just how QE works.
QE is not just about bank reserves. In fact, the bank reserve effect is arguably the least important feature of QE – although that opinion may not exactly warm the cockles of monetarist hearts. The paper appropriately refers to reserves as the “by-product” of QE (a concept I invoked in a back and forth here with Scott Sumner in his early blogging days, roughly 5 years ago).
There are additional points made about QE that are notable – that the central bank isn’t giving the banks “free money” for example. Again, a full appreciation of this aspect requires an understanding of banking system liability effects of QE – including potential or actual pricing effects on the liability side (this may become more of an issue after zero bound lift off has commenced for those systems that are currently parked next to the zero bound).

Critique 1
http://www.themoneyillusion.com/?p=26355#
I recall that Paul Krugman was once criticized for saying banks can “lend out” reserves. I generally don’t say things like that because I ignore banks. But there was nothing wrong with Krugman’s claim. Yes, it’s true that when money is lent out and the borrower withdraws the loan as cash, the borrower does not literally “hold reserves.” So the BoE is technically correct. But that’s a meaningless distinction, as it’s all base money, and reserves are just the name given to base money when held by banks, and cash is the name given to base money held by non-banks.
One common misconception is that banks act simply as intermediaries, lending out the deposits that savers place with them. In this view deposits are typically ‘created’ by the saving decisions of households, and banks then ‘lend out’ those existing deposits to borrowers, for example to companies looking to finance investment or individuals wanting to purchase houses.
In fact, when households choose to save more money in bank accounts, those deposits come simply at the expense of deposits that would have otherwise gone to companies in payment for goods and services. Saving does not by itself increase the deposits or ‘funds available’ for banks to lend. Indeed, viewing banks simply as intermediaries ignores the fact that, in reality in the modern economy, commercial banks are the creators of deposit money. This article explains how, rather than banks lending out deposits that are placed with them, the act of lending creates deposits — the reverse of the sequence typically described in textbooks.
I recall that once when Krugman was faced with this sort of argument he said something to the effect of “it’s a simultaneous system.” Banking is an industry that provides intermediation services. Banks have balance sheets with assets and liabilities. It makes no sense to say that one side of the balance sheet causes the other. If people want to borrow more, then bank interest rates on loans and deposits adjust in such a way as to provide a new equilibrium, probably with a larger balance sheet. But that’s equally true of the situation where people want to hold larger amounts of bank deposits. It’s completely symmetrical. Consider the real estate broker industry. Does more people buying houses cause more people selling houses, or vice versa?
Critique 2
So in equilibrium, when the actual stock of base money is equal to the quantity of base money demanded, the stock of broad money must be a multiple 1/r of the stock of base money. And if the central bank shifts the supply function of base money $1 to the right, that must increase the equilibrium stock of broad money by $(1/r). Just like the first-year textbook says it will!
Now you might object that modern central banks don't care about the stock of base money (except when they are doing QE), and target things like inflation instead (except for 8 week periods when they target an interest rate). OK. But if the central bank wanted a temporary increase in the inflation rate, and so a permanent rise in the price level, it would need to shift the supply function of base money, to create a permanent rise in the monetary base, and a permanent rise in broad money, and the textbook money multiplier would tell us that broad money would increase by 1/r times the increase in base money.
One simple (first-year textbook) general theory to rule them all!
What is the underlying problem here? Why do monetary economists resist this very simple and very general theory of monetary policy? The underlying problem is revealed in this quote:
"Like reductions in Bank Rate, asset purchases are a way in which the MPC can loosen the stance of monetary policy in order to stimulate economic activity and meet its inflation target."
It assumes that interest rates are a measure of the "stance of monetary policy". If interest rates were an adequate measure of the "stance of monetary policy", the Bank of England would not need QE. And you cannot define the stance of monetary policy by taking some sort of average of interest rates and QE. A permanent increase in the target price level would mean a permanent increase in the money base but would have no obvious implications for interest rates. A permanent increase in the inflation target would mean a permanent increase in the growth rate of the money base but would mean higher nominal interest rates. There is no monotonic mapping from loose monetary policy into low interest rates. Thinking about monetary policy in terms of interest rate policy just doesn't work. It doesn't work in theory, and it doesn't work in practice. That's why the Bank of England is doing QE, and having to re-introduce the old general theory as a special theory of how monetary policy works.
